Identification (ID + MDP) : Pb récupération saisie avec une GList

**Mona Lisa** · 01/02/2014, 17h09

Bonjour tout le monde

J'ai un problème au niveau de la récupération de saisie avec GTK+ : je souhaite faire une fenêtre d'identification sauf que j'ai du mal a récupérer 2 saisie dans une fenêtre... Je ne sais pas si j'ai été assez clair mais dans tout les cas je vous mets le code

(tout du moins le contenu du fichier idetification.c ^^ :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Voili voilou et dans les trois cas je n'obtiens pas d'erreur dans le build log ou le build message (je travaille avec Code::Blocks). Le programme cesse simplement de fonctionner après que j'ai appuyer sur Entrée ou clicker sur le bouton Ok. Je vais aussi faire une petite vidéo YT pour vous montrer explicitement le problème. Le lien va suivre

Merci pour votre aide future qui j'espère va m'aider à résoudre ce problème ^^

Coordialement, Mona Lisa ;-P
